Opinions on the below areas (Mumbai)

We (Myself, Wife and two boys) will be in Mumbai by July/August and have been given the option of three areas to live in, which are;

-Kohinoor City-Bandra West-Powai

What are your opinions on these three areas for a young family, first time in Mumbai? My wife will be working at the American School of Bombay in the lower year groups so the Kohinoor area is only a 10 minute walk to the campus, but the other areas also have their positives according to their documents sent by the school.
